"That's a long four hours, too, boy," Zimmer said.
Zimmer's health issues began approximately a month ago.
"I was gone, I was in a diabetic coma," Zimmer said. "If my wife doesn't wake me up, I'm still sleeping. My blood sugar was 20 and they rushed me to the hospital. My son was with me. My wife. That's where it all started.
"She tried to wake me up at noon, she couldn't wake me. She called my son, who lives in the same building we do. He came over and neither one of them could wake me up. He said, 'Call 911.'"
Zimmer, 81, still doesn't feel great, but he's headed in the right direction.
"This is the best I've felt," Zimmer said. "They say dialysis, the more you take it the stronger you get. I get out of breath if I walk too far, so my wife brought me down here [to Tropicana Field] and she will come and get me after a little while."
Zimmer smiled just being back at the ballpark.
"I'm back where I'm supposed to be," Zimmer said. "What games I've been watching, [wow]!"
